{
libgomp: Use TLS storage for omp_get_num_teams()/omp_get_team_num() values When thinking about GOMP_teams3, I've realized that using global variables for the values returned by omp_get_num_teams()/omp_get_team_num() calls is incorrect even with our right now dumb way of implementing host teams. The problems are two, one is if host teams is used from multiple pthread_create created threads - the spec says that host teams can't be nested inside of explicit parallel or other teams constructs, but with pthread_create the standard says obviously nothing about it. Another more important thing is host fallback, right now we don't do anything for omp_get_num_teams() or omp_get_team_num() which was fine before host teams was introduced and the 5.1 requirement that num_teams clause specifies minimum of teams, but with the global vars it means inside of target teams num_teams (2) we happily return omp_get_num_teams() == 4 if the target teams is inside of host teams with num_teams(4). With target fallback being invoked from parallel regions global vars simply can't work right on the host. So, this patch moves them to struct gomp_thread and propagates those for parallel to child threads. For host fallback, the implicit zeroing of *thr results in us returning omp_get_num_teams () == 1 and omp_get_team_num () == 0 which is fine for target teams without num_teams clause, for target teams with num_teams clause something to work on and for target without teams nested in it I've asked on omp-lang what should be done. 2021-11-11 Jakub Jelinek <jakub@redhat.com> * libgomp.h (struct gomp_thread): Add num_teams and team_num members. * team.c (struct gomp_thread_start_data): Likewise.

openmp: Add omp_set_num_teams, omp_get_max_teams, omp_[gs]et_teams_thread_limit OpenMP 5.1 adds env vars and functions to set and query new ICVs used as fallback if thread_limit or num_teams clauses aren't specified on teams construct. The following patch implements those, though further work will be needed: 1) OpenMP 5.1 also changed the num_teams clause, so that it can specify both lower and upper limit for how many teams should be created and changed the meaning when only one expression is provided, instead of num_teams(expr) in 5.0 meaning num_teams(1:expr) in 5.1, it now means num_teams(expr:expr), i.e. while previously we could create 1 to expr teams, in 5.1 we have some low limit by default equal to the single expression provided and may not create fewer teams. For host teams (which we don't currently implement efficiently for NUMA hosts) we trivially satisfy it now by always honoring what the user asked for, but for the offloading teams I think we'll need to rethink the APIs; currently teams construct is just a call that returns and possibly lowers the number of teams; and whenever possible we try to evaluate num_teams/thread_limit already on the target construct and the GOMP_teams call just sets the number of teams to the minimum of provided and requested teams; for some cases e.g. where target is not combined with teams and num_teams expression calls some functions etc., we need to call those functions in the target region and so it is late to figure number of teams, but also hw could just limit what it is willing to create; in that case I'm afraid we need to run the target body multiple times and arrange for omp_get_team_num () returning the right values 2) we need to finally implement the NUMA handling for GOMP_teams_reg 3) I now realize I haven't added some testcase coverage, will do that incrementally 4) libgomp.texi needs updates for these new APIs, but also others like the allocator 2021-10-11 Jakub Jelinek <jakub@redhat.com> gcc/ * omp-low.c (omp_runtime_api_call): Handle omp_get_max_teams, omp_[sg]et_teams_thread_limit and omp_set_num_teams. libgomp/ * omp.h.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * omp_lib.f90.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * omp_lib.h.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * libgomp.h (gomp_nteams_var, gomp_teams_thread_limit_var): Declare. * libgomp.map (OMP_5.1): Export omp_get_max_teams{,_}, omp_get_teams_thread_limit{,_}, omp_set_num_teams{,_,_8_} and omp_set_teams_thread_limit{,_,_8_}. * icv.c (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): New functions. * env.c (gomp_nteams_var, gomp_teams_thread_limit_var): Define.

openmp: Add omp_set_num_teams, omp_get_max_teams, omp_[gs]et_teams_thread_limit OpenMP 5.1 adds env vars and functions to set and query new ICVs used as fallback if thread_limit or num_teams clauses aren't specified on teams construct. The following patch implements those, though further work will be needed: 1) OpenMP 5.1 also changed the num_teams clause, so that it can specify both lower and upper limit for how many teams should be created and changed the meaning when only one expression is provided, instead of num_teams(expr) in 5.0 meaning num_teams(1:expr) in 5.1, it now means num_teams(expr:expr), i.e. while previously we could create 1 to expr teams, in 5.1 we have some low limit by default equal to the single expression provided and may not create fewer teams. For host teams (which we don't currently implement efficiently for NUMA hosts) we trivially satisfy it now by always honoring what the user asked for, but for the offloading teams I think we'll need to rethink the APIs; currently teams construct is just a call that returns and possibly lowers the number of teams; and whenever possible we try to evaluate num_teams/thread_limit already on the target construct and the GOMP_teams call just sets the number of teams to the minimum of provided and requested teams; for some cases e.g. where target is not combined with teams and num_teams expression calls some functions etc., we need to call those functions in the target region and so it is late to figure number of teams, but also hw could just limit what it is willing to create; in that case I'm afraid we need to run the target body multiple times and arrange for omp_get_team_num () returning the right values 2) we need to finally implement the NUMA handling for GOMP_teams_reg 3) I now realize I haven't added some testcase coverage, will do that incrementally 4) libgomp.texi needs updates for these new APIs, but also others like the allocator 2021-10-11 Jakub Jelinek <jakub@redhat.com> gcc/ * omp-low.c (omp_runtime_api_call): Handle omp_get_max_teams, omp_[sg]et_teams_thread_limit and omp_set_num_teams. libgomp/ * omp.h.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * omp_lib.f90.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * omp_lib.h.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * libgomp.h (gomp_nteams_var, gomp_teams_thread_limit_var): Declare. * libgomp.map (OMP_5.1): Export omp_get_max_teams{,_}, omp_get_teams_thread_limit{,_}, omp_set_num_teams{,_,_8_} and omp_set_teams_thread_limit{,_,_8_}. * icv.c (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): New functions. * env.c (gomp_nteams_var, gomp_teams_thread_limit_var): Define.

libgomp: Use TLS storage for omp_get_num_teams()/omp_get_team_num() values When thinking about GOMP_teams3, I've realized that using global variables for the values returned by omp_get_num_teams()/omp_get_team_num() calls is incorrect even with our right now dumb way of implementing host teams. The problems are two, one is if host teams is used from multiple pthread_create created threads - the spec says that host teams can't be nested inside of explicit parallel or other teams constructs, but with pthread_create the standard says obviously nothing about it. Another more important thing is host fallback, right now we don't do anything for omp_get_num_teams() or omp_get_team_num() which was fine before host teams was introduced and the 5.1 requirement that num_teams clause specifies minimum of teams, but with the global vars it means inside of target teams num_teams (2) we happily return omp_get_num_teams() == 4 if the target teams is inside of host teams with num_teams(4). With target fallback being invoked from parallel regions global vars simply can't work right on the host. So, this patch moves them to struct gomp_thread and propagates those for parallel to child threads. For host fallback, the implicit zeroing of *thr results in us returning omp_get_num_teams () == 1 and omp_get_team_num () == 0 which is fine for target teams without num_teams clause, for target teams with num_teams clause something to work on and for target without teams nested in it I've asked on omp-lang what should be done. 2021-11-11 Jakub Jelinek <jakub@redhat.com> * libgomp.h (struct gomp_thread): Add num_teams and team_num members. * team.c (struct gomp_thread_start_data): Likewise.

libgomp: Use TLS storage for omp_get_num_teams()/omp_get_team_num() values When thinking about GOMP_teams3, I've realized that using global variables for the values returned by omp_get_num_teams()/omp_get_team_num() calls is incorrect even with our right now dumb way of implementing host teams. The problems are two, one is if host teams is used from multiple pthread_create created threads - the spec says that host teams can't be nested inside of explicit parallel or other teams constructs, but with pthread_create the standard says obviously nothing about it. Another more important thing is host fallback, right now we don't do anything for omp_get_num_teams() or omp_get_team_num() which was fine before host teams was introduced and the 5.1 requirement that num_teams clause specifies minimum of teams, but with the global vars it means inside of target teams num_teams (2) we happily return omp_get_num_teams() == 4 if the target teams is inside of host teams with num_teams(4). With target fallback being invoked from parallel regions global vars simply can't work right on the host. So, this patch moves them to struct gomp_thread and propagates those for parallel to child threads. For host fallback, the implicit zeroing of *thr results in us returning omp_get_num_teams () == 1 and omp_get_team_num () == 0 which is fine for target teams without num_teams clause, for target teams with num_teams clause something to work on and for target without teams nested in it I've asked on omp-lang what should be done. 2021-11-11 Jakub Jelinek <jakub@redhat.com> * libgomp.h (struct gomp_thread): Add num_teams and team_num members. * team.c (struct gomp_thread_start_data): Likewise.

libgomp: Use TLS storage for omp_get_num_teams()/omp_get_team_num() values When thinking about GOMP_teams3, I've realized that using global variables for the values returned by omp_get_num_teams()/omp_get_team_num() calls is incorrect even with our right now dumb way of implementing host teams. The problems are two, one is if host teams is used from multiple pthread_create created threads - the spec says that host teams can't be nested inside of explicit parallel or other teams constructs, but with pthread_create the standard says obviously nothing about it. Another more important thing is host fallback, right now we don't do anything for omp_get_num_teams() or omp_get_team_num() which was fine before host teams was introduced and the 5.1 requirement that num_teams clause specifies minimum of teams, but with the global vars it means inside of target teams num_teams (2) we happily return omp_get_num_teams() == 4 if the target teams is inside of host teams with num_teams(4). With target fallback being invoked from parallel regions global vars simply can't work right on the host. So, this patch moves them to struct gomp_thread and propagates those for parallel to child threads. For host fallback, the implicit zeroing of *thr results in us returning omp_get_num_teams () == 1 and omp_get_team_num () == 0 which is fine for target teams without num_teams clause, for target teams with num_teams clause something to work on and for target without teams nested in it I've asked on omp-lang what should be done. 2021-11-11 Jakub Jelinek <jakub@redhat.com> * libgomp.h (struct gomp_thread): Add num_teams and team_num members. * team.c (struct gomp_thread_start_data): Likewise.

omp_get_team_num (void)
{
libgomp: Use TLS storage for omp_get_num_teams()/omp_get_team_num() values When thinking about GOMP_teams3, I've realized that using global variables for the values returned by omp_get_num_teams()/omp_get_team_num() calls is incorrect even with our right now dumb way of implementing host teams. The problems are two, one is if host teams is used from multiple pthread_create created threads - the spec says that host teams can't be nested inside of explicit parallel or other teams constructs, but with pthread_create the standard says obviously nothing about it. Another more important thing is host fallback, right now we don't do anything for omp_get_num_teams() or omp_get_team_num() which was fine before host teams was introduced and the 5.1 requirement that num_teams clause specifies minimum of teams, but with the global vars it means inside of target teams num_teams (2) we happily return omp_get_num_teams() == 4 if the target teams is inside of host teams with num_teams(4). With target fallback being invoked from parallel regions global vars simply can't work right on the host. So, this patch moves them to struct gomp_thread and propagates those for parallel to child threads. For host fallback, the implicit zeroing of *thr results in us returning omp_get_num_teams () == 1 and omp_get_team_num () == 0 which is fine for target teams without num_teams clause, for target teams with num_teams clause something to work on and for target without teams nested in it I've asked on omp-lang what should be done. 2021-11-11 Jakub Jelinek <jakub@redhat.com> * libgomp.h (struct gomp_thread): Add num_teams and team_num members. * team.c (struct gomp_thread_start_data): Likewise.
